摘要
通过大田试验,研究了不同留叶数目和方式对烤烟K326生长及产、质量的影响,结果表明:主茎留叶数相同时,随着杈烟留叶数的增加,株高逐渐增加,而茎围与节距变化不大;不同留叶数对下部叶片影响较大,相同的主茎留叶数,随着杈烟留叶数的增加,下部叶片的长和宽有逐渐增加的趋势,对中、上部叶片的影响则较小;总留叶数相同的情况下,留叶方式除对株高有一定影响外,对烤烟其他性状及经济指标影响较小;留叶数偏少(总留叶20片),对烟叶的产量和产值会有不利影响,而留叶数偏多(总留叶26片),产量虽有所增加,但均价、上等烟比例将受到不利影响。综合产、质量效益,K326以有效留叶数24片为最佳。
Throngh field experiment,the effects of the number and method of different remained leaf on the growth,leaf yield and quality of flue-cured tobacco variety K326 were studied. The results showed that the height of the flue-cure tobacco increased with increasing remained leaf number of brance tobacco when remained leaf number of the stems was the same. Girth and pitch of stem were influenced little. Remained leaf number had great impact on the lower leaves. The length and width of the lower leaves increased with increasing remained leaf number of brance tobacco when remained leaf number of the stems was the same, but the middle and upper leaf of flue-cured tobacco were not appreciably affected. The method of remained leaf had a small influ- ence on economic index and other characters except plant height when total remained leaf number was the same. The yield and output would be decreased by keeping less leaves per plant, but keeping more leaves would influence on the average price and the rate of high and middle class leaf. Generally,keeping twenty four leaves per plant for K326 was appropriate.
